Description
MK-677 is an orally active growth hormone secretagogue that selectively activates GHSR-1a to induce sustained elevations of endogenous GH and IGF-1. Its non-peptidic structure enables high oral bioavailability and extended activity, providing a consistent endocrine response without direct pituitary receptor desensitization. This compound is utilized in research exploring metabolic modulation, body-composition dynamics, sleep-architecture influences, and ghrelin-mediated neuroendocrine pathways. Designed exclusively for controlled scientific investigation, MK-677 serves as a model agent for studying long-duration GH/IGF-1 axis manipulation.

What are Peptides?
Peptides are short chains of amino acids—building blocks of proteins—that help support various functions in the body. They play a key role in cell signaling, tissue repair, muscle growth, and overall wellness. Thanks to their targeted effects, peptides are commonly used in skincare, sports performance, and anti-aging products.
